Workpiece screwing control system and method

The invention relates to a workpiece screwing control system. The workpiece screwing control system comprises a system server, a workpiece identifier, a screwing machine controller and a system controller, wherein the system controller is used for sending a control instruction to the screwing machine controller, reading a state of the screwing machine controller, acquiring a screwing curve and final screwing result information of a workpiece, sending an instruction to the system server, acquiring workpiece screwing judgment information, judging whether a final screwing result of a current workpiece is qualified or not and uploading the screwing curve information of the current workpiece, the screwing result information and workpiece counting information to the system server. The inventionalso discloses a workpiece screwing control method. By real-time monitoring of the workpiece screwing process, omnibearing control of screwing operation is achieved, a false fault brought by only judgment of a final screwing
